Product details
Overview
P6KE16CA-E3/73 from Vishay General Semiconductor is a bidirectional Transient Voltage Suppressor (TVS) diode in DO-15 package, designed for clamping voltage transients on signal or power lines. It features 600 W peak pulse power (10/1000 μs), 16 V nominal breakdown voltage (VBR = 15.2–16.8 V at IT = 1.0 mA), and clamps to ≤22.5 V at 26.7 A peak pulse current - used for protecting MOSFETs, ICs, and sensor interfaces against ESD and inductive switching surges.
For engineers reviewing the P6KE16CA-E3/73 datasheet, P6KE16CA-E3/73 pinout, P6KE16CA-E3/73 application, or P6KE16CA-E3/73 equivalent, key selection criteria include bidirectional clamping capability, DO-15 mechanical compatibility, 175 °C max junction temperature, low leakage (<1.0 μA at 13.6 V), and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, enabling symmetric clamping in both polarities without polarity marking. Its 20 °C/W junction-to-lead thermal resistance supports sustained surge handling when mounted on PCB copper pours or leads with ≥0.375" length.
Clamping behavior is defined by two key voltage thresholds: stand-off voltage VWM = 13.6 V (max reverse leakage 1.0 μA), and clamping voltage VC = 22.5 V at IPPM = 26.7 A - ensuring robust protection margin below typical 24 V system rail limits while maintaining fast response time (<1 ns).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 15.2 V / 16.8 V at 1.0 mA test current - defines reliable avalanche initiation range under transient stress |
| VWM | 13.6 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 μA |
| VC @ IPPM | 22.5 V at 26.7 A - peak clamped voltage during 10/1000 μs surge, limiting downstream component stress |
| PPPM | 600 W - peak pulse power rating per single 10/1000 μs waveform, derated above 25 °C ambient |
| TJ max | +175 °C - enables operation in under-hood automotive or industrial environments without thermal shutdown |
| RθJL | 20 °C/W - low thermal resistance from junction to lead supports high-repetition surge handling with proper lead heatsinking |
| AEC-Q101 | Qualified - validated for automotive electronics per stress test requirements including HTOL, TC, and HTRB |
Pinout & Package
Package: DO-15 (DO-204AC), axial-leaded, molded epoxy case meeting UL 94 V-0 flammability rating. Matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards. No polarity marking - bidirectional operation confirmed.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (unmarked ends) | Bidirectional avalanche junction terminals | Either end functions identically - no cathode band; symmetrical clamping in positive/negative transients |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable, repeatable avalanche characteristics over lifetime and temperature cycling |
| 600 W peak pulse power (10/1000 μs) | Withstands common ISO 7637-2 pulse 1/2/5a surges without degradation when properly mounted |

| AEC-Q101 qualified | Validated for automotive powertrain, body control, and ADAS modules requiring extended reliability |
| Solder dip 275 °C max. 10 s | Compatible with standard wave soldering processes without parametric shift or delamination |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16CA | DO-214AA package, 600 W rating, VBR = 17.8–19.7 V, VC = 26.0 V @ 23.1 A | Surface-mount footprint; higher clamping voltage reduces protection margin on 24 V rails | Select when board space constraints require SMD mounting and thermal design accommodates lower surge current density |
| 1.5KE16CA | DO-201AD package, 1500 W rating, VBR = 15.2–16.8 V, VC = 25.0 V @ 60 A | Larger through-hole package; higher power rating suits infrequent but extreme surges (e.g., lightning) | Choose for legacy designs requiring higher single-pulse energy absorption where DO-15 mechanical fit is not mandatory |
Compared with P6KE16CA-E3/73, SMBJ16CA offers SMT compatibility at the cost of higher clamping voltage and reduced surge current handling, while 1.5KE16CA delivers 2.5× peak power in a larger package - making P6KE16CA-E3/73 optimal for cost-sensitive, space-constrained 24 V systems needing AEC-Q101 validation.

FAQ
What is the breakdown voltage tolerance for P6KE16CA-E3/73?
The P6KE16CA-E3/73 has a specified breakdown voltage range of 15.2 V to 16.8 V at 1.0 mA test current, representing ±5.6% tolerance around the nominal 16 V rating. This tight VBR window ensures consistent clamping onset across production lots and supports predictable circuit protection margins in designs using P6KE16CA-E3/73.
Is P6KE16CA-E3/73 suitable for automotive applications?
Yes, P6KE16CA-E3/73 is AEC-Q101 qualified and rated for operation from –55 °C to +175 °C junction temperature, making it suitable for under-hood and cabin-mounted automotive electronics. Its bidirectional clamping, DO-15 mechanical robustness, and validated reliability per automotive stress tests confirm its use in ECUs, sensor modules, and body control units where P6KE16CA-E3/73 is deployed.
How does the clamping voltage of P6KE16CA-E3/73 compare to its stand-off voltage?
P6KE16CA-E3/73 has a maximum stand-off voltage VWM of 13.6 V and clamps to 22.5 V at 26.7 A peak pulse current - resulting in an 8.9 V clamping margin. This 65% overvoltage headroom ensures safe operation below 24 V system rails while providing effective transient suppression without false triggering during normal operation of P6KE16CA-E3/73.
What is the maximum leakage current specification for P6KE16CA-E3/73 at rated VWM?
At its maximum stand-off voltage of 13.6 V, P6KE16CA-E3/73 exhibits a maximum reverse leakage current of 1.0 μA at 25 °C ambient. This ultra-low leakage preserves signal integrity in high-impedance sensor interfaces and minimizes standby power loss in battery-powered systems where P6KE16CA-E3/73 is integrated.
Can P6KE16CA-E3/73 be used in place of unidirectional TVS diodes like P6KE16A?
No - P6KE16CA-E3/73 is explicitly bidirectional (denoted by "CA" suffix) and lacks polarity marking, whereas P6KE16A is unidirectional with cathode band. Substituting P6KE16CA-E3/73 for P6KE16A may cause unintended conduction in DC-biased circuits. Always verify polarity requirements before selecting P6KE16CA-E3/73 in place of unidirectional variants.
